Has anyone had the transmission slip on their E-320?

I have a 1995 E-320 and the transmission has started slipping during acceleration.

Is this common? Why would it be slipping and how can I fix this? Repair cost?

Any insight would be much appreciated.

Thank you,

 

Oh dear.

What exactly do u mean by slipping? Staying too long in a gear? taking too long to shift?

It might be a "transmission service" which is something defined by your mechanic...

It might have to be a new or rebuilt tranny exchange, which can be extemely expensive. Like a grand or two..

Check out www.adsitco.com or any other mercedes benz parts place to get exact parts. Remember, that doesn't include labor.

 

chupper,

The transmission is taking too long to shift. It has trouble getting into the next gear and sometimes just slips until I back off from the accelerator pedal.

Does anyone else have this experience?

Thanks,

 

I was having this problem just very recently on my 89 300E. It seemed to lag while shifting at a certain gear at a certain RPM. About a week after noticing it, my dad wrecked the car, so its gone now...

Good luck to ya! At least I kept your post on top !

 

It was a bad (cracking, exposed wires) wiring harness causing the engine to misfire.

 

One of my buddies had trouble with his transmission where it would slip very badly going into first gear then slip a little bit going into second gear. Having no idea how to work on transmissions or what symtoms mean we thought it was dead. He took it to AAMCO and they fixed it, it turns out fluid was leaking and had drained to low for the torque converter to catch or something. They fixed the leak and put new fluid in. The best part though was AAMCO only charged $30. So try going there, they should be honest, at least this one is.

 

have a mechanic change the fluid and filter, and adjust the bowden cable.

That should help, and while he is changign the tranny fluid, he will be able to find out about the clutch packs to see if they are wearing out.

I just fixed that same problem in my 94 E320. It started to "flare" when shifting 2/3. You can remove the valve body and install a kit with springs to alter the pressure in the K1K2 value. It's not a big job, just messy. If you change your own transmission filters then you can do this. If not take it to a service centre, with the parts and have them do it. The transmission does not have to be removed. The job takes 1.5 hours DIY. Solved the problem for me nicely. The man to speak to is Mario @ Independent Transmission Services in Miami. (305) 666-3544. He was very helpful.....and knows his Mercedes transmissions.

I have a 91 300E24v, m104 engine with the same flaring you described.Is the solution you posted temporary?Can you describe the proceedure a little bit more?What does it (k1k2) look like?
This is been an ongoing problem for me and I would Appreciate your help.
Thanx in advance ,Chris.

 

The best advice I can give is to call Mario, above. (His Spanish is better than his English). He will send you the spring set ($75) with reasonably easy instructions. There are also 2 small holes to drill. But you have to be able to remove the valve body in the transmission which is up inside. You get to that by removing the pan and the filter. If you are confident enough to do that you shouldn't have any trouble. If not, the other option is to take it to a service centre (not MB, too much $$) with the parts and instructions. (Of course, give them Mario's phone # in case). It takes 2hrs to repair and it is permanent. Of course, to save money you could remove the valve body and take that to a service centre and let them change the bits, drill the holes and you put it back in. It's worth the trouble. Good Luck

 

Brian thanx for your reply,unfortunatly I am in Australia.
How were you sure that this would cure your flaring problem?
I rang Mercedes Australia and they said they had two types of kits and said the best thing to do is to take the old one off so they can match it,only problem is that I dont know what im looking for.I am a very good DIY and you seem to be my low cost solution!
I took the car to a mercedes shop and they said the transmission had to be rebuilt (2500-4500AUD)but somehow I didnt trust him.
What is the exact name of the kit?
Thanx again.

 

G'Day....I lived in Wahroonga for 10 years till '93. I forgot how bloody expensive things were there!!! Got lottsa friends in Syndey and the area.
OK, so you need to check the transmission number. It is probably 722.3** or 722.4**. I would also suggest you buy a 12 month online subscription to ALLDATADIY for that car.......it's the 104 engine, which is the same as mine but they didn't come out in NA 'till late "93 in the sedan. I think the coupe (CE) was '92, so the transmission should be the same. It may be a good thing to get that info.from MB there. They will have all those specs. Once you have deteremined which transmission you have the guts will be the same regardless of left or right drive. Actually. let me give you a link to my ALLDATA site. Send me an email to bpmcl@cogeco.ca with your return and I will send you the password. Don't want to post it here.
Anyway, once in the AllData site you can get a diagram of the valve body for that transmission with instructions on how to remove it. But...you are still going to need to get the kit from Mario....forget those bandits at MB OZ!! Plus the parts from Mario will work, no worries, if the transmission numbers match. But even if they don't, get the right number and he will be able to direct you. He is a wizard, I mean the name of his company is GermanAuto-Trans!! He will send the springs, a whole series of them, cello taped on a photocopy of the valve body with lots of good direction. Once you get it out, if you want to telephone me I can talk you through taking it apart( time zones!!). It comes out as one piece but you need to open it....no big deal, any mechanic should be able to that. I can't remember anybody in North Sydney who I could recommend, but there must be an MB club or something there who will help. All you need to do is take a good mechanic the valve body with diagrams (AllData)and he should be able to fix it. Just let all the fluid drain out first. When you do remove it let the transmission drain over night AFTER you remove the filter. Take the filter out very carefully not to tilt it...it's just full of fluid. And the same with the valve body.....take the bolts out and let it come straight down.....it too is full of fluid. (No need to drain the converter unless you want to) Catch as much fluid as you can so you will know how much to put back in...pretty important not to over fill it. Of course, put in a new filter and pan gasket. But you really do need to talk with Mario once you get the trans. number Tell him you have soandso transmission # ----------- with a flare from 2 / 3rd, or whatever. He'll give you the right advice and part. He works with people, by phone, from all over.
How many KM on the car? Can you email a pic? Bye for now.

 

Brian, I just sent an email to you with a bit of info. and I hope to send some pics soon.

To everyone that knows their transmissions. I have a 1987 300D Turbo and i'm not sure if this is normal or not but the transmission seems to shift with a hard jolt when going from first to second gear and sometimes second to third. I've rode in 1981 300D's that did the same thing. Is this normal or is there something wrong with the transmission? Thanx in advanced

 

Oh yeah!!!!

 

There is obviously something wrong then according to your reaction. My question is whats wrong with it? Does it just need a filter change or is it something much bigger because there's fluid and all, just that it does the strange shift.

 

No, what I meant was that's normal. the Germans like to refer to it as a "positive" shift. Anyway, there are a couple of spring swaps that you can put in the valve body but that requires a higher level of DIY. If your confident you can then give Mario a call in Miami at GermanAutoTrans. (305) 667-4208. He'll sell you the right kit with instructions. Good Luck
